In contrast to conventional coupler design approaches, this synthesis method uses an additional process characterization step, which computes the electrical behaviour of these coupled lines in a given process layer stackup via even and odd mode simulations. Thus, the extracted behaviour information is used to determine the geometric values for a parametrized passive structure. Afterwards, a model and numerical based optimization is performed to improve the design with respect to a predefined specification target. To demonstrate this method, a Marchand balun was designed. The measured results of this balun show a maximum phase imbalance of 2° between 125 and 170 GHz and an insertion loss of maximum 2 dB for the entire D-Band.","PeriodicalId":184822,"journal":{"name":"2020 IEEE Radio and Wireless Symposium (RWS)","volume":"498 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126659446","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the measurement results, 1-dB input compression point of 11dBm is obtained at 60 GHz with conversion gain of -9.5 dB with overall DC power consumption of 17.7 mW. The maximum gain of -6.5 dB is achieved at 53 GHz with 3-dB RF bandwidth of 50-60 GHz for LO drive of -2 dBm. IF 3-dB bandwidth is around 5.5 GHz. The chip occupies the area of 483 μm by 482 μm.

Designs aim to save energy yet satisfy real-time service and availability, thus necessitating power solutions. Main components typically stay in sleep modes until a wake-up event occurs, such as a timeout. Communication is often scheduled for these active periods, leaving designs susceptible to idle listening and wasted energy. An attractive approach for energy optimization and sustainability for low-power devices is wake-up radio (WUR) for the ability to wake-up devices over-the-air. This work proposes the system integration of two recent prototypes: a sensor platform for industrial IoT and a 2.4GHz WUR. Preliminary results demonstrate this proof-of-concept.","PeriodicalId":184822,"journal":{"name":"2020 IEEE Radio and Wireless Symposium (RWS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129785618","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The PA comprises a common-source (CS) input stage, a CS first gain stage and a two-way CS second gain stage, followed by an eight-way CS output stage using miniature triple Y-shaped divider and combiner. Positive feedback is used at both the input and the first gain stages to enhance gain, which in turn leads to a higher output power (Pout) and power-added efficiency (PAE). At each branch’s input terminal, the triple Y-shaped current combiner can convert the serial RL load to the optimal load impedance (corresponding to the optimal Pout and PAE) of the output stage transistors.

The phase control can be used to both beamform the reflected signal in a desired direction and modulate data onto a signal of opportunity for short range communications. The simplicity of the unit element and control routing enables the elements to be electrically small (~λ/6 spacing).

In addition to solving the time domain boundary conditions between neighboring samples, we optimize the coefficients of piecewise polynomials in frequency domain to achieve good in-band and out-of-band frequency responses while maintaining the low-latency and low-complexity properties of a conventional CSI. To demonstrate the advantage, a 200 MHz instantaneous bandwidth (iBW) signal consisted of two 100 MHz 5G New Radio (NR) waveforms is adopted in simulation. The results show that the proposed CSI can achieve a normalized mean square error (NMSE) of -65.6 dB compared to -37.1 dB obtained with the conventional CSI. The proposed method is not penalized by the aliasing effects due to Nyquist sampling, as the ratio of sampling rate to signal bandwidth approaches 2.5x.","PeriodicalId":184822,"journal":{"name":"2020 IEEE Radio and Wireless Symposium (RWS)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131655153","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
